f). Chapter 56One factor favoring rapid population growth by an introduced species is theabsence of the predators, parasites, and pathogens that controlled its population inthe region where it evolved. In a short essay (100-150 words), explain how evolutionby natural selection would influence the rate at which native predators, parasites,and pathogens in a region of introduction attack an introduced species.Assignment 3: Chapter QuestionsChapter 1:1). For each of the following themes discussed in this chapter, give an example notmentioned in the book: Emergent Properties, Environmental Interactions,Energy Transfer, Structure and Function, Cellular Basis of Life, Genetic Basisof Life, Feedback Regulation, and Evolution.2). Re-read pages 20-22, “Investigating Mimicry in Snake Population,” anddetermine the following: a). Hypothesisb). Experiment: Control and Variablec). Datad). ConclusionChapter 52:1). Identify the natural biome in which you live, and summarize its abiotic andbiotic characteristics. Do these reflect your actual surroundings? Explain.Chapter 53:1). Consider two rivers: One is spring fed and has a constant water volume andtemperature year-round; the other drains a desert landscape and floods anddries out at unpredictable intervals. Which river would you predict is morelikely to support many species of iteroparous animals? Why?2). How has the growth of Earth’s human population changed in recent decades.Answer in terms of growth rate and the number of people added each year.
